Tveit will play Gareth, described as “a Republican operative whose wit is only trumped by his pragmatism. The Legislative Director to a top Republican senator, Gareth is smart, hard-working and ultimately responsible for helping to save the world.”

BrainDead, slated to premiere in summer 2016, follows Winstead’s Laurel, “a young, fresh-faced Hill staffer whose first job in Washington, D.C. leads her to discover two things: The government has stopped working, and alien spawn have come to Earth and eaten the brains of a growing number of congressmen and Hill staffers.”

“We’re thrilled that Aaron will be joining BrainDead,” said the Kings, in a statement. “We’re huge fans of his work – he’s spectacular on stage and screen – and think he’ll be a fantastic opponent-slash-love-interest for Mary Elizabeth Winstead.”
